Gunicorn Https Setup Guide

Introduction

Gunicorn is a Python WSGI HTTP server that is easy to configure and highly performant. It is a popular choice for hosting web applications in production. In this guide, we will walk through the steps to set up Gunicorn to serve HTTPS traffic.

Prerequisites

Before you begin, you will need the following:

• A Python web application
• Gunicorn installed on your system
• A SSL certificate and private key

Step 1: Create a Gunicorn Configuration File

Create a new file named `gunicorn.conf` in your application's directory. This file will contain the Gunicorn configuration settings. Add the following code to the file: ``` bind = '127.0.0.1:8000' workers = 3 timeout = 60 ```

In this configuration file, we have specified the IP address and port on which Gunicorn should listen for incoming connections, the number of worker processes to use, and the timeout period for inactive connections.

Step 2: Configure HTTPS

Add the following lines to the `gunicorn.conf` file to enable HTTPS: ``` keyfile = '/path/to/your_private_key.pem' certfile = '/path/to/your_certificate.pem' ```

Replace `/path/to/your_private_key.pem` and `/path/to/your_certificate.pem` with the actual paths to your SSL certificate and private key files.

Step 3: Start Gunicorn

To start Gunicorn, run the following command: ``` gunicorn --config gunicorn.conf your_app:app ``` Replace 'your_app:app' with the name of your WSGI application object. Your application should now be accessible via HTTPS at the specified IP address and port.

Additional Notes

Here are some additional notes to keep in mind: If you are using a reverse proxy such as nginx, you will need to configure it to forward HTTPS traffic to Gunicorn. Gunicorn can be configured to use different settings for development and production environments. You can use the `gunicorn -h` command to view all available configuration options.
